ore
daily, and the recent monthly profits have been, it is stated, upwards
of 15,000 pounds sterling. These are also controlled by British
capitalists, as is the "Esperanza" Mine of El Oro, it is stated, which
has produced since 1895 a value of 4-1/2 millions sterling, with a
profit of nearly 2-1/2 millions. The "Dos Estrellas" Mine is yet
another example of this successful district. It is said to have made
profits since 1902 of 2-1/2 millions sterling, and to have ore for
future work in large quantities. It is interesting to note that this
excellent performance has been made on ground which had been condemned
by mining experts![34]

Other prosperous mining concerns in different parts of the country,
generally owned by native capital, include the "Real del Monte" Mines
of Pachuca, elsewhere described: the "Maravellas and Anexas Mining
Company," principally silver producing; the "Santa Gertrude Mines," a
silver property; "La Blanca and Anexas," gold and silver--all of which
are in the Pachuca district. The Parral mining district, in Chihuahua,
is one which has recently received attention, although it is not new,
having yielded silver from the middle of the sixteenth century. Some
six millions sterling represent the investments in the district during
the last fifteen years in these mines. The famous Penoles Mine is among
the most prosperous in the country. This is a
lead-gold-silver-producing enterprise in Durango, at Mapimi, worked
first in Colonial times. Now it owns large smelters, a line of railway,
and an extensive property. In 1907 this enterprise produced 58,000
kilograms of silver, 504 kilograms of gold, and has an annual output of
some 20,000 tons of lead.

In Sonora various gold-mining properties are at work. Among them is the
Consolidated Goldfields of Mexico, Ltd., British capital: the
Creston-Colorado Mines, worked by American capital, including the old
British-worked Minas Prietas mines: there are other gold mining
companies old and new under British enterprise, and the Bufa and the
Trinidad Companies, producing gold, silver, and copper. In fact, the
State of Sonora is a rich field for the working of the precious metals,
and offers great possibilities.

In Chihuahua are some important gold and silver-producing enterprises,
among them the Greene Gold-Silver Company, owned by Americans, and the
Palmarejo Mines, a British enterprise. Inde
